Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0091] Figure 1 This is a schematic structural diagram of a dehumidifier according to an embodiment of the present invention; as shown below. Figure 1 As shown, and refer to Figures 2-22This utility model provides a dehumidifier for dehumidifying air in the environment. The dehumidifier includes a housing 100, a heat exchanger 200, and a fan. The housing 100 defines an accommodating space, and has a first air inlet 101, a second air inlet 102, a third air inlet 103, and an air outlet communicating with the accommodating space. The first air inlet 101, the second air inlet 102, and the third air inlet 103 are respectively located on three different side walls of the housing 100. The air outlet is located on the top wall of the housing 100. The heat exchanger 200 is disposed within the accommodating space. The fan is also disposed within the accommodating space and is configured to force air into the accommodating space through the first air inlet 101, the second air inlet 102, and the third air inlet 103, exchange heat with the heat exchanger 200, and then exit from the air outlet. The heat exchanger 200 is configured to at least cool the air. For example, heat exchanger 200 is configured to first cool the air as it flows through, condensing moisture in the air, and then heat the cooled air, minimizing the temperature difference between the air before it enters the housing 100 and after it exits the housing 100. In some alternative embodiments, heat exchanger 200 is used only to cool the air as it flows through.

[0092] In the dehumidifier of this embodiment, because the casing 100 has multiple air inlets located on different side walls of the casing 100, it allows as much airflow as possible to enter the accommodating space. Furthermore, the use of circumferential air inlet and top air outlet facilitates smooth airflow. Figure 22 As shown, this improves the heat exchange efficiency of the heat exchanger 200, thereby increasing the dehumidification efficiency. Furthermore, the multiple air inlets located on different side walls of the casing 100 facilitate the placement of the dehumidifier. In confined spaces, at least two side walls can be used for air intake, with upward airflow, making the dehumidifier suitable for various applications and enhancing its versatility.

[0093] In some embodiments of this utility model, such as Figures 1-7 As shown, the dehumidifier also includes a compressor 400, a support assembly 500, and a drawer-type water tank 600. The support assembly 500 is disposed within the housing 100 and has a spacer 510, on which a water receiving cavity 511 and a clearance space 512 are provided. A heat exchanger 200 is located above the water receiving cavity 511, and condensate flows along the heat exchanger into the water receiving cavity 511 and is collected there. The drawer-type water tank 600 is disposed within the receiving space and below the spacer 510, configured to receive water from the water receiving cavity 511. A perforation is provided at the bottom of the water receiving cavity 511, through which condensate flows into the drawer-type water tank 600. In some alternative embodiments, water is introduced into the drawer-type water tank 600 from the bottom of the water receiving cavity 511 via a water guide pipe.

[0094] The compressor 400 is disposed within the accommodating space, passing through the clearance space 512. Part of the compressor 400 is located below the partition 510, and part is located above the partition 510. The fan is preferably an axial flow fan 300, located above the partition 510 and below the air outlet; the axial flow fan 300 is configured to draw in air from its lower side and blow it upwards. This arrangement allows for a compact dehumidifier structure.

[0095] In some embodiments of this utility model, such as Figures 1-7 As shown, the first air inlet 101, the second air inlet 102, and the third air inlet 103 are all located on the upper side of the spacer 510. In some alternative embodiments of this utility model, a portion of the first air inlet 101 is located on the upper side of the spacer 510, and a portion is located on the lower side of the spacer 510; a portion of the second air inlet 102 is located on the upper side of the spacer 510, and a portion is located on the lower side of the spacer 510; a portion of the third air inlet 103 is located on the upper side of the spacer 510, and a portion is located on the lower side of the spacer 510.

[0096] In some embodiments of this utility model, such as Figures 1-3 As shown, the first air inlet 101, the third air inlet 103, and the second air inlet 102 are connected along the circumferential direction of the housing 100, further expanding the air inlet area. In some other embodiments of this utility model, the first air inlet 101 is formed by multiple air holes, the second air inlet 102 is formed by multiple air holes, and the third air inlet 103 is formed by multiple air holes. All the air holes are evenly distributed on the side wall of the housing 100 along the circumferential direction of the housing 100.

[0097] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, along the circumferential direction of the casing 100, the heat exchanger 200 includes a first heat exchange section 210, a second heat exchange section 220, and a third heat exchange section 230. Specifically, the first heat exchange section 210, the third heat exchange section 230, and the second heat exchange section 220 are arranged sequentially along the circumferential direction of the casing 100. The first heat exchange section 210 is located at the first air inlet 101, the second heat exchange section 220 is located at the second air inlet 102, and the third heat exchange section 230 is located at the third air inlet 103. The heat exchanger 200 is U-shaped, making the internal structure more compact, increasing the heat exchange area, and improving the dehumidification effect. In some alternative embodiments of this utility model, the heat exchanger 200 includes only the first heat exchange section 210 and the second heat exchange section 220. In other alternative embodiments of this utility model, the heat exchanger 200 includes only the first heat exchange section 210.

[0098] Moreover, in some embodiments of this utility model, such as Figure 8 and Figure 9As shown, along the thickness direction of the heat exchanger 200, the heat exchanger 200 includes multiple heat exchange layers, which are sequentially arranged along the thickness direction of the heat exchanger 200. The multiple heat exchange layers may include at least one first heat exchange layer 250 and at least one second heat exchange layer 260. The second heat exchange layer 260 is disposed inside the first heat exchange layer 250 and serves as a condensation section configured to heat the air. The first heat exchange layer 250 serves as an evaporation section configured to cool the air. In some embodiments of this invention, the multiple heat exchange layers may further include at least one third heat exchange layer, which is disposed between the first heat exchange layer 250 and the second heat exchange layer 260. The upper part of the third heat exchange layer is configured to heat the air, and the lower part is configured to cool the air; or, the lower part of the third heat exchange layer is configured to heat the air, and the upper part is configured to cool the air. Each pair of adjacent heat exchange layers may be in contact to reduce volume, or each pair of adjacent heat exchange layers may be spaced apart. This invention, by adjusting the shape of the heat exchanger 200, not only reduces the size of the machine, making it easier for users to place, use, and store, but also allows some of the condensate to be dripped directly onto part of the condenser to enhance heat exchange and achieve energy saving. Since the water is dripped at the rear end of the condenser, the condenser temperature has already decreased, avoiding the risk of further evaporation of the water. In addition, there is another condenser behind it to prevent water from being blown out to the air outlet.

[0099] In some alternative embodiments of the present invention, along the height direction of the heat exchanger 200, the heat exchanger 200 includes an upper heat exchange section and a lower heat exchange section, the lower heat exchange section serves as a condensation section and is configured to heat the air, and the upper heat exchange section serves as an evaporation section and is configured to cool the air.

[0100] In some embodiments of this utility model, such as Figure 10As shown, a connecting area 513 is provided on the partition 510. The connecting area 513 is located above the drawer-type water tank 600. The connecting area 513 is configured so that air from the drawer-type water tank 600 enters the upper part of the partition 510 through the connecting area 513. When the axial flow fan 300 is working, the gas below the partition 510, i.e., the gas near the drawer-type water tank 600, flows upward through the connecting area 513 under the drive of the axial flow fan 300. The cooling capacity of the condensate in the drawer-type water tank 600 is carried away by the airflow and continues to exchange heat with the air after passing through the condenser, thereby reducing the outlet air temperature. It also helps to remove the heat generated by the nearby compressor 400 and dissipate heat from the compressor 400. In other words, by setting the connecting area 513, the axial flow fan 300 located above and the drawer-type water tank form a certain ventilation circulation, allowing the cooling capacity of the condensate in the water tank to circulate upward.

[0112] In some embodiments of this utility model, such as Figure 18 and Figure 19As shown, in order to store as much condensate as possible, make reasonable use of space, and place the water tank as close as possible to the compressor 400 for heat dissipation, the first bracket 520 has a space plate 521 opposite to the opening of the water tank mounting space 540. The space plate 521 is recessed into the opening of the water tank mounting space 540, and the compressor 400 is disposed in the recess of the space plate 521. The rear wall of the drawer-type water tank 600 is configured to conform to the shape of the space plate 521 so that the rear of the drawer-type water tank 600 has a first water storage space 610 and a second water storage space 620. The first water storage space 610 and the second water storage space 620 are located on both sides of the compressor 400.

In other words, the compressor 400 is positioned in a recessed area, allowing full utilization of its opposite sides. The drawer-type water tank 600 is positioned correspondingly at its rear end, forming water storage sections near the sides of the compressor 400, partially enclosing it. This allows the cooling capacity within the water tank to be more effectively used for heat dissipation from the compressor 400. In other words, the shape of the water tank must be integrated with the shape of the compressor 400, forming a small air cavity in the middle. By utilizing the lower temperature of the condensate in the water tank, the cooling capacity of the condensate is used to cool the compressor 400, achieving energy savings and improved efficiency.

[0113] In some embodiments of this utility model, such as Figure 18 and Figure 19 As shown, the bottom wall of the drawer-type water tank 600 has an upwardly recessed handle groove at the front end, and the lower end of the front wall of the drawer-type water tank 600 has a notch communicating with the handle groove, facilitating the formation of a concealed handle. The drawer-type water tank 600 adopts a drawer-style design, which facilitates user disassembly and cleaning, while also improving the overall aesthetics of the dehumidifier, making its appearance more integrated and attractive. A water tank cover 630 is provided at the top opening of the drawer-type water tank 600 to minimize condensate overflow, further preventing condensate from affecting the compressor 400, control box 700, etc., ensuring electrical safety, and also preventing condensate from corroding structural components.

[0114] In some embodiments of this utility model, such as Figure 7 , Figure 18 and Figure 19As shown, the water tank cover 630 is equipped with a storage slot 632 for accommodating the dehumidifier's casters 800 and maintenance tools. When the storage slot 632 extends into the drawer, it is inside the water tank. A water passage is provided at the bottom of the storage slot, allowing the water tank cover 630 to form a storage space without affecting the water tank's capacity. Water in the drawer-type water tank enters the storage slot 632 through the water passage. The water tank cover 630 is equipped with a flip-up handle 640 for easy emptying. The material of the water tank cover 630 is not limited to transparent material, allowing for easy observation of the water level and cleanliness inside the tank. Furthermore, the drawer-type water tank 600 is equipped with a float structure for water level control via sensors. A transparent window 611 is provided on the front wall of the drawer-type water tank 600.

[0115] In some embodiments of this utility model, such as Figure 8 and Figure 9 as well as Figure 20 and Figure 21 As shown, the distances between the central axis of the axial fan 300 and the first heat exchange section 210, the second heat exchange section 220, and the third heat exchange section 230 are all equal. The distance between the central axis of the axial fan 300 and the vertical central axis of the heat exchanger 200 is less than or equal to 1 / 10 of the distance between the central axis of the axial fan 300 and the third heat exchange section 230. This arrangement allows the airflow to pass fully through the heat exchanger 200, improving heat dissipation and promoting smooth airflow.

[0116] In some embodiments of this utility model, such as Figure 8 and Figure 9 as well as Figure 20 and Figure 21 As shown, the axial flow fan 300 includes fan blades 310, an external rotor drive motor 320, and a guide ring 330. The middle portion of the fan blades 310 defines a motor cavity. The external rotor drive motor 320 is disposed within the motor cavity. An air outlet grille 900 is provided at the air outlet, and the stator of the external rotor drive motor 320 is mounted on the air outlet grille 900. The guide ring 330 is disposed on the outer side of the fan blades 310. The upper end of the guide ring 330 is connected to the air outlet. The lower end of the guide ring 330 is located below the fan blades 310 and within the space enclosed by the heat exchanger 200. The ratio of the distance L2 between the plane containing the lower end of the guide ring 330 and the lower end face of the heat exchanger 200 to the outer diameter of the guide ring 330 is between 1 / 2 and 13 / 10. The distance between the plane containing the lower end of the guide ring 330 and the upper end face of the heat exchanger 200 is within 10 mm. The distance between the outer wall of the air guide ring 330 and the inner wall of the heat exchanger 200 is within 10mm.

[0117] In some embodiments of this utility model, such as Figure 8 and Figure 9 as well asFigure 20 and Figure 21 As shown, the air outlet grille 900 includes a receiving cylinder 910, a display input device 920, and a ventilation grille 930. The opening of the receiving cylinder 910 faces upward, and a computer board is installed inside the receiving cylinder 910. The computer board is electrically connected to the external rotor drive motor 320. The receiving cylinder 910 is located directly above the external rotor drive motor 320. The stator is mounted on the receiving cylinder 910. The display input device 920 is located at the upper opening of the receiving cylinder 910 to cover the receiving cylinder 910, and is configured to display and receive input. The placement of the display input device 920 is advantageous for users to operate the dehumidifier, as the display is easily observed and convenient for user operation, ensuring user convenience and intuitiveness. Through a reasonable layout, the operation of the dehumidifier becomes simpler and more intuitive. Furthermore, the display control area is located directly above the center of the axial flow fan 300, where the airflow is relatively small, which can prevent the temperature of electrical components from rising due to the outlet air temperature. The ventilation grille 930 is located around the display input device to allow airflow to pass through. The top cover 120 is fixedly connected to the second bracket 530 at the air outlet by screws. The air outlet grille 900 is snapped into the top cover 120 and covers the screws.

[0118] In some embodiments of this utility model, such as Figure 6 As shown, the ratio of the distance L1 between the lower end of the air guide ring 330 and the upper end of the compressor 400 to the distance L2 between the lower end of the air guide ring 330 and the lower end face of the heat exchanger 200 is 1 / 5 to 1 / 3. This arrangement allows for a more compact layout between the compressor 400 and other components such as the heat exchanger 200 and the axial fan 300, further reducing the overall volume of the dehumidifier body, improving transportation and storage efficiency, and without affecting the air delivery of the axial fan 300. The air delivery is smooth, the heat exchange efficiency is high, and it also facilitates the heat dissipation of the compressor 400.
